Abstract
Spreader formula line feeding rifle for a kind of steel-making, belong to smelting iron and steel technical field, comprise rifle body and spreader, rifle body and spreader are refractory materials and make, and spreader is fixed on rifle body lower end, in rifle body, is provided with conduit, described conduit is arranged at Qiang Ti center, its upper end is provided with joint, and conduit upper side is provided with conduit air intake, on conduit rifle body around, is provided with some ventpipes.The utility model is by the effect of many ventpipes and spreader, makes the protective gas that is blown into more even, effectively intercepted the oxidation of airborne oxygen composition to cored-wire; Spreader can block the molten steel of splash, has effectively increased security, has reduced molten steel loss, and has reduced the pollution to surrounding environment.
Description
Technical field:
The utility model belongs to smelting iron and steel technical field, is specifically related to spreader formula line feeding rifle for a kind of steel-making.
Background technology:
In steelmaking process, adopt when throwing in bulk alloy material solution deoxidation of molten steel and realizing alloying, bad owing to melting, alloy recovery is low, constituent adjustment is accurate not, can make molten steel inner quality be difficult to improve.In recent years, development along with technology, people propose to apply wire-feeding technique and address the above problem, and are mainly that application feeding wire machine continuously adds different types of cored-wire in molten steel by oriented tube, carry out deoxidation, desulfurization, alloying and change steel inclusion form.At present, the kind of cored-wire mainly contains pure Ca line, CaSi line, FeTi line, Al line, S line, FeB line, C line, pure Mg line, magnesium alloy wire and RE line etc.But the elements such as Ca wherein, Mg, Al and Ti belong to the element that oxyphie power is very strong, while using pure metal or its alloy to add molten steel, very easily produce oxidation, splash is serious, easily there is conduit mouth dry slag, even block phenomenon, but also exist the rate of recovery low, the problems such as absorption of nitrogen by steel and alloy fine setting difficulty.
In order to address these problems, some technician improve the line feeding rifle of existing feeding wire machine, are mainly, in line feeding process, molten steel is blown into shielding gas.Gas shield technique and the device thereof of a kind of Steel Plant molten steel line feeding alloying, refining are disclosed in Chinese patent CN1206375C; employing is blown into the method for shielding gas to ladle feeding line machine wire conduit; the specific gas shield of surrounding's formation region at alloy wire and ladle liquid level; can prevent alloy and molten steel oxidation by air; improve alloy recovery; avoid liquid level to seethe, cleaning molten steel, improves the quality of products.The shortcoming of this invention is the specific protective atmosphere of jetting and form between the gas that and molten steel face in bottom; because gas syphonic effect can also be brought air in protective atmosphere into and go; destroy protective atmosphere; can not well reach not oxidation by air of cored-wire; prevent the object of molten steel face suction nitrogen, and because gas direct injection is to liquid level, surrounding is blocked without any; the splash producing is large, cannot guarantee worker safety.
Utility model content:
The problem existing for solving prior art, the utility model proposes a kind of can effectively anti-cored-wire oxidation, the spreader formula line feeding rifle for steel-making of anti-molten steel splash.
For achieving the above object, the utility model is by the following technical solutions: spreader formula line feeding rifle for a kind of steel-making, comprise rifle body and spreader, rifle body and spreader are refractory materials and make, and spreader is fixed on rifle body lower end, in rifle body, is provided with conduit, described conduit is arranged at Qiang Ti center, its upper end is provided with joint, and conduit upper side is provided with conduit air intake, on conduit rifle body around, is provided with some ventpipes.
The joint of described conduit upper end is threaded joint.
Described ventpipe quantity is 2~12.
Described ventpipe is Raoul tubular type ventpipe.
The utility model beneficial effect: by the effect of many ventpipes and spreader, make the protective gas that is blown into more even, effectively intercepted the oxidation of airborne oxygen composition to cored-wire; Spreader can block the molten steel of splash, has effectively increased security, has reduced molten steel loss, and has reduced the pollution to surrounding environment.
Accompanying drawing explanation:
Fig. 1 is the structural representation of an embodiment of the present utility model;
Fig. 2 is the sectional elevation of the rifle body of Fig. 1.
Wherein: 1-conduit, 2-conduit air intake, 3-cored-wire, 4-rifle body, 5-ventpipe, 6-spreader, 7-joint.
Embodiment:
Below in conjunction with drawings and Examples, the utility model is described in further details:
As shown in Fig. 1~Fig. 2, spreader formula line feeding rifle for a kind of steel-making, comprise the bowl type spreader 6 that rifle body 4 and the rim of a bowl are downward, rifle body 4 and spreader 6 are refractory materials and make, can be aluminum fire resistant materials or siliceous refractory [material, spreader 6 is fixed on rifle body 4 lower ends, in rifle body 4, be provided with conduit 1, described conduit 1 is arranged at rifle body 4 centers, its upper end is provided with joint 7, conduit 1 is connected in feeding wire machine by joint 7, and there is cored-wire 3 to penetrate conduit 1 by joint 7 centre holes, conduit 1 upper side is provided with conduit air intake 2, by the interior importing shielding gas of conduit air intake 2 conductive pipe 1, can more effectively completely cut off air, described rifle body 4 also comprises six Raoul formula ventpipes 5, ventpipe 5 is arranged on around conduit 1.The joint 7 of conduit 1 upper end is threaded joint, and convenience is connected and disconnection with feeding wire machine.
In steelmaking process, cored-wire 3 can continuously be sent from feeding wire machine, the conduit 1 of the line feeding rifle by the present embodiment joins among molten steel, in line feeding process, conduit air intake 2 and ventpipe 5 can be access in shielding gas, shielding gas can completely cut off airborne oxygen composition, make cored-wire 3 not oxidized under high-temperature condition, bowl type spreader 6 can make shielding gas more effective to the isolation action of air, and when high pressure gas or cored-wire 3 cause molten steel splash, spreader 6 can stop the molten steel of most of splash, reduce the loss of molten steel and protected staff's safety around.
